Many reasons are involved in this combination. First, as bone cancer is not easy to determine, doctors may have to use biopsy to have a first look, but it needs to be paired with x rays and different scnas to confirm and do it more acurately. Some bone infection may cause symptoms and imaging results that could be confused with bone cancer.Have in mind that <span>bone metastases can usually be diagnosed based on x-rays and other imaging tests.A combination of all the scans and X rays can help to detect bone cancer in different places of the body, as every method can show tumors in specific parts of the skeleton. </span>
Plasmids, they are mostly found in bacterial cells and they r the cause of antibiotic resistance in bacteries :)
The correct answer is it decreases genetic diversity only by reducing population size.
<span>
The great explanation for this is a bottleneck effect, which is an extreme example of genetic drift. The bottleneck effect occurs when the size of a population is reduced due to a catastrophe. When it happens, only a small, random number of individuals survive the event and pass through the bottleneck. Thus, the genetic composition of the random survivors is now the genetic composition of the entire population which means that the genetic diversity is reduced.</span>
